1. DMAIC

2. SEA

3. PDSA

4. DMADV

The correct answer is: PDSA

The methodology known as the Deming-Shewhart cycle is referred to as PDSA, which stands for Plan, Do, Study, Act. This cycle is a critical framework in continuous improvement processes and emphasizes iterative learning and adaptation based on feedback. In the PDSA cycle, the first step is planning an action or intervention, then implementing it in the "Do" stage. After executing the plan, the next step involves studying the results to see if the desired improvements have been achieved. Finally, in the "Act" stage, decisions are made based on the analysis, leading to either adopting the changes permanently, testing further adjustments, or revisiting the planning phase if results were unsatisfactory. Understanding this framework is essential in quality management and continuous improvement efforts, reinforcing the importance of learning through cycles of experimentation.
